Geodata of Wunthou IDP Site, Awerial County, Lakes State, South Sudan

This map illustrates satellite-detected shelters and other buildings at Minkaman IDP Site, as seen by the WorldView-1 satellite on 10 May 2014. People displaced from the fighting around Bor have established in different IDP Sites at Minkaman, in Awerial County, Lakes state, in South Sudan. Note that the camp occupied areas along the western bank of Nile River including 393 shelters approximately. A larger settlement is nearby in and around the town of Minkaman, about 17 kilometres to the south. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

UNOSAT datasets and maps are produced using a variety of methods. In general, analysts closely review satellite imagery, often comparing two or more images together, and determine notable changes between the images. For damage assessments, refugee or IDP assessments, and similar analyses, these changes are then manually documented in the vector data by the analyst. For flood extractions, landcover mapping and similar analyses, a variety of automated remote sensing techniques are used to extract the relevant information which is then reviewed and revised as necessary by the analyst. In all cases, resulting data is then loaded into a standardized UNOSAT geodatabase and exported asshapefiles for dissemination.

Caveats / Comments

This is a preliminary assessment and has not yet been validated in the field. It is important to consider the characteristics of the source imagery used in the analyses when interpreting results. For damage assessments it should be noted that only significant damage to the structural integrity of the buildings analyzed can be seen in imagery, while minor damage such as cracks or holes may not be visible at all. For flood extractions using radar data it is important to note that urban areas and highly vegetated areas may mask the flood signature and result in underestimation of flood waters. Users with specific questions or concerns should contact unosat@unitar.org to seek clarification.
